I've transplanted one of them, bit it looked a bit soon so I'll wait more for the others. Moved under my TS1000 which they loved right away. More lst applied on the branches, I'll try to keep the low in height.
@jarxle, knowing that I could handle it, I would do 4 11l pots in a 100x100, that would be ideal for me. Is a lot of water every feed tho, but the space should be perfect for that.
